With no idea what your compression ratio is its hard to say, but that's a big cam, if you've got 9.5:1 compression that could be what it makes. Is this with a stock style starter or mini-starter (mini starter is worth about 20 PSI in my experience)

Are you sure this cam is 260/268 @ .050 and not 260/268 advertised? If its really at .050 what cam did you have in it before?

Verify TDC on the balancer is TDC on #1. You do have the timing light connected to #1 right?

If it really is 50 degrees I agree with Mr P body your cam is off a tooth. EDIT I see you said you degreed it in at 102 though. Double check your valve lash, EOIC!



Zippy - how did you find your vacuum leak under the intake, and what did you need to correct?
